Nearly 40 - should I be worried after 4 months of TTC with no success?

Just that really. Period is due on Sunday and pretty sure I am not pregnant as no symptoms. This will be the 4th month we have tried. I'm nearly 40 and DH is 46. Should we be worried? When do you seek help? I thought it would have happened now but on the other hand we haven't been trying that long. We both already have 2 kids each (none together) so were fertile at one point.

Guidelines are that if you are over 35 your gp should offer tests and investigations if you've not conceived within 6 months. So give it another coupe before you go. Hopefully you won't need to, it can take a bit longer when you're older.

I'm 40 this summer, and pg with #2. It took us 8 months of TTC 2nd time round. We conceived on month 2 of using clear blue digital ov sticks, which I highly recommend as it took all the guess work out of when I ovulated.

thanks all. Sanch/Cheeky, we used an ovulation kit last month and I got the two lines which is why I'm surprised I didn't conceive as we definitely DTD at the right time. Kicking myself we didn't start trying ages ago. We've been together nearly 5 years and only just around to deciding to TTC.
